A bloody catastrophe shattered a thousand-year-old dynasty. As the sole surviving prince, Li Yuan fled in disguise to the Southern Border, where he joined the Gu Master lineage and accidentally awakened the Gu Insect Fusion System.

Outside, various warlords, demons, monsters, and martial sects were all hunting him down, hoping to use his royal blood as the key to unlock the Martial God’s Treasure left behind by the founding emperor.

Martial God’s Treasure? No!

Li Yuan chose to lie low and refine Gu.

【Added Longevity Grass – You’ve synthesized the Rebirth Gu】

【Added Sands of Time – You’ve synthesized the Everchanging Gu】

【Added the Empress’s Blood – You’ve synthesized the Imperial Majesty Gu】

…

Thirty long years passed.

The invincible Martial Emperor, the overlord of demons and monsters across the seas, and the power-hungry warlords finally found Li Yuan.

That day—the undefeated Martial Emperor fell, the demon overlord perished, and all the kings and lords knelt!

That day—the world revered me like a god! Feared me like a celestial!

I am the Martial God—

And the Gu Immortal!!
